So yeah... Is there a way of doing " measuring " electricity and not using probes? Laser perked?

Discussion Overview
The discussion centers around the possibility of measuring electricity without the use of physical probes. Participants explore various methods and devices that might allow for non-contact measurement of electrical quantities, including voltage and current.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants inquire about non-probe methods for measuring electricity, suggesting the use of lasers or other innovative techniques.
- One participant mentions non-contact hand-held AC voltage detectors, noting that they function as threshold detectors without providing quantitative measurements.
- Another participant asks if there are instruments capable of providing quantitative values without physical contact.
- A participant introduces clamp ammeters as devices that can measure current without direct contact, explaining that they detect the magnetic field around a conductor.
- One participant shares a link discussing the operation of non-contact voltage sensors, implying their relevance to the topic.
- Another participant references electron beam probers used in the semiconductor industry, suggesting a specialized application of non-contact measurement techniques.
Areas of Agreement / Disagreement
Participants express varying degrees of interest in non-contact measurement methods, but there is no consensus on the effectiveness or availability of quantitative measurement devices without probes. Multiple competing views and methods are presented.
Contextual Notes
Some limitations include the lack of clarity on the specific types of measurements participants are interested in and the varying definitions of "measuring electricity." The discussion does not resolve the feasibility of the proposed methods.
Who May Find This Useful
Individuals interested in electrical measurement techniques, non-contact sensing technologies, or applications in the semiconductor industry may find this discussion relevant.

There are non-contact hand-held AC voltage detectors like the one below. But they are just threshold detectors, without a quantitative readout. They use the person as the "ground" reference for the AC E-field detection...3301 said:

Any instrument that can check quantitative value ? :) Not even star track could grasp this concept :)

There are devices called clamp ammeters that can measure the current flowing through a wire. The ammeter makes no physical contact with the wire -- it senses the magnetic field around the conductor.
